The Keys of Knowledge

While all knowledge is accessible at all times our access to it is impaired by our physical limitations. Our ability to process and understand the information we are searching for. A comparison I like to make is where someone is registering in a large hotel. Where the clerk then gives them a room number, then presents them with all the keys to all the rooms unmarked. They now must thru a process of elimination try each key until they happen upon the one that opens the door.
